EDMONTON -- Alberta's police watchdog is investigating after a Mountie opened fire on a Red Deer woman who RCMP say had fled from their officers. 

On Aug. 24 around 2:30 a.m., police say they found a vehicle near 51 Avenue and 33 Street in Red Deer that had been involved in a criminal flight from police the day before. 

Police say "an interaction occurred that led to the officer firing his service pistol." 

The Alberta Serious Incident Response Team has been called in to investigate.

According to ASIRT, video from the police vehicle shows the Mounie approach the white Ford Edge on foot and the woman drive at the officer "who fired his service weapon as he moved out of the way." 

David Thomas Mathias told CTV News Edmonton he heard four gun shots.

"I was awaken by a pop, a very loud pop," he said.

"It was a bit alarming because we don't expect to hear shots in the middle of the night, so I got up, went out onto the balcony...in just a matter of moments police were there."

Neither ASIRT nor police have said how many times the police member fired their gun. 

The driver fled the scene and officers later found the vehicle abandoned in the Easview neighbourhood.

The 22-year-old woman who police say was driving the vehicle was found with a leg wound and taken to hospital. When she was discharged, she was taken into police custody. 

ASIRT has asked anyone in the area of 33 Street and 50 Avenue round the time of the shooting and witnessed the confrontation or has any other related info to call investigators at 403-592-4306.
